Definitions
- the invention relates to a device for ventilation of a steering wheel, especially in the grip area of the steering wheel rim by feeding of air via a duct system to the steering wheel rim and air outflow through a large number of outlet openings distributed over the steering wheel rim.
- DE 21 64 976 A1 describes a device for heating or Cooling of vehicle steering wheels have become known, in which an in Steering wheel and channel system formed in the steering column from an in Existing warm or cooling air source vehicle in the area of the vehicle Steering wheel rim and the steering wheel spokes guided and over a variety is blown out of openings.
- the connection of the air control system in the Steering wheel and in the steering column with the warm or cold air source of the Vehicle is operated via a two-way valve.
- a steering device is from German utility model 9204354 become known for motor vehicles, in which the actual steering wheel has a support body with a non-slip casing and with a steering tube is connected. In the area of the supporting body is one Temperature control device is provided, which acts on the casing and is supplied with energy via the steering tube. According to one embodiment Should the temperature of the steering wheel on the air conditioning or The vehicle is ventilated from the inside. These are on the steering wheel Ventilation holes provided through the steering tube with ventilation or the air conditioning system of the vehicle. So much for this steering device to be heated by means of heated or cooled air, it has the same disadvantages as those from DE 21 64 976 A1 well-known establishment. Like the carrying device and the casing such tempered steering wheels should be executed and how that required air guidance system can be integrated into the steering wheel, cannot be found in German utility model 9204354.
- the invention proposes that Steering wheel rim and the transition areas to the steering wheel spokes through to form two half-shells, which are connected to one another at the edge as well are fixed relative to the supporting skeleton of the steering wheel and some Form air duct, the at least one air inlet opening and has a plurality of air outlet openings.
- the half-shells can be positively and non-positively connected and be provided with ergonomically designed recessed handles. Together with the steering wheel skeleton, all requirements regarding Strength and accident safety can be optimally met without the Manufacturing process is complicated or expensive.
- the two Half-shells 4 and 5 are designed so that they are together at the edges connected and attached to the supporting skeleton.
- the transition areas are designed so that they have at least one Air intake opening 8 can accommodate and cross-section to the Customized foam around the steering wheel spokes adapted are.
- the shaping of the half shells is done with regard to the rest on the various steering wheel functions, and without further ado ergonomically designed recessed grips 10, in particular in the area of lower half shell 5 come into consideration.
- FIG. 3 shows an embodiment of the inventive concept, in which the lower half-shell 5 with transition areas 2 and Steering wheel spokes 3 in one piece from a suitable die-casting process
- Light metal alloy is made.
- the upper half shell 4 can also from a light metal alloy processed by die casting consist or of a processed by injection molding thermoplastic.
- the shape of the upper half shell 4 does not differ from that according to Figures 1 and 2.
- the Shape of the lower half shell 5 with ergonomically designed Handle recesses 10 do not differ from that according to FIG. 1 and 2.
- the air inlet opening is correspondingly 8 and the air outlet openings 9 as in Figures 1 and 2 educated.
- the half-shells 4 and 5 show how a Fan 13 into the air inlet opening 8 of the upper half shell 4 is inserted.
- the half-shells 4 and 5 form an integrated air supply duct 12, which merges into the air duct.
- the half shells 4 and 5 comprise the skeleton 6 and are on the skeleton belonging spokes 3 supported such that they with the steering wheel skeleton form a mechanical unit, all in motor vehicle operation occurring stresses on the steering wheel is sufficient.
- the half shells 4 and 5 are covered with an air-permeable fabric 11, the outside of a conventional steering wheel cover 14 made of plastic, leather or the like is covered. This sheath is like the fabric 11 air-permeable training.
- Figure 6 shows the placement of a fan 13 in the transition area 2 between the steering wheel rim 1 and spokes 3 of the upper half shell 4 in an embodiment according to Figures 3 and 4, in which the lower Half-shell 5 in one piece with a die-cast from a light metal alloy manufactured steering wheel skeleton 6 is formed.
- the lower half-shell 4 also in one piece with a sheet metal manufactured steering wheel skeleton to which a hub area is molded in terms of casting technology.
- the half-shells 4 and 5 are air-permeable Fabric 11 covered, on the outside still a usual, not closer designated steering wheel cover 14 made of plastic, leather or the like. is applied.
- FIGS. 5 and 6 have the advantage that only a very short air control system is required and that therefore the flow losses can be minimized.
- air inlet opening 8 is provided with a single fan 13, and there are all other transition areas 2 from the steering wheel rim 1 closed to the steering wheel spokes 3.
- two can or more fans 13 are provided.
- the only decisive factor is that two, the steering wheel rim 1 and Transitional areas 2 to the steering wheel spokes 3 half shells 4, 5 are provided, which are connected to one another at the edge and which form the air duct 7.
